Has maintained secure document storage and efficient data distribution with peer-to-peer architecture

The functions or features in Cassandra that I have found most valuable are that it is a distributed system similar to Mongo. It's good enough for comparison with another SQL database, so it's smooth and organized for distributed database system. The peer-to-peer architecture in Cassandra is helpful for network decentralization, and I have already introduced that feature. Cassandra features in peer-to-peer as well as another monitoring, so basically, it's good enough for our service. The tunable consistency level in Cassandra is good, and we are using that feature already. In terms of built-in caching and lightweight transactions in Cassandra, the transaction level is good, and it's optimized, so there are no more issues in that database. Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there. Additionally, the database monitoring system or auditing system is well-comparable with other database systems, so we are actually happy to be using this Cassandra database.

Automation Engineer at a educational organization with 11-50 employees

Unified course data has streamlined our AI study assistant and still needs better large-scale search

There can be compute spikes when we scale up, which we noticed during our intake season while processing millions of records. Massive similarity searches on a lot of vectors can spike the database CPU and potentially slow down API requests, so we had to move to a higher plan in Supabase for handling this during our intake season. There is no native hybrid search yet, which can combine keyword search and vector search. Supabase supports both, but combining them requires writing a custom Postgres function, while dedicated tools on other platforms allow you to do that out of the box. On some level, we face indexing complexity with Supabase Vector because although vectors expedite searches, we need to use indexes such as HNSW or IVF Flat. Tuning these indexes in Postgres requires advanced knowledge, and we needed a dedicated Supabase expert or to hire someone capable of understanding these complex queries and set this up for us, making it not a plug-and-play solution for a massive scale project with tens of millions of vectors. Vectors are stored in Postgres, and we can perform a lot of similarity searches on millions of vectors, which can spike database CPU and potentially slow down the app, but apart from that, everything seems positive.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable features of this solution are its speed and distributed nature."

"Cassandra is good, it's better than CouchDB, and we are using it in parallel with CouchDB, as Cassandra looks better and is more user-friendly."

"I am satisfied with the performance; so far it has done fairly well and there haven't been any complaints."

"The solution's database capabilities are very good."

"I'd rate the solution ten out of ten."

"The technical evaluation is very good."

"I am getting much better performance than relational databases."

"We have experienced zero downtime using Cassandra, it is highly stable."

More Cassandra pros

"Supabase Vector has positively impacted our organization quite a lot, as we moved away from Pinecone to a unified platform where we store relational and vectorized data together, reducing automation times and eliminating the hassle of managing and maintaining two separate databases in sync."

"The platform's role-level security feature is quite effective for spatial data management."

"Supabase Vector rapidly increases the speed and efficiency with which I search through a database, helping with my data analysis tasks."

"Supabase enables us to lower the skill floor while keeping the ceiling high."

"Supabase Vector is easy to set up and cost-effective because the alternative is Firebase, which requires a credit card."

"Supabase enables us to lower the skill floor while keeping the ceiling high."

Cons

"The solution doesn't have joins between tables so you need other tools for that."

"One of the issues with the solution is that you cannot drop write like you're able to in MongoDB and MySQL, where you can join tables."

"While Cassandra can handle NoSQL, I think there should be more flexibility for whole schema design when data is stored in wide columns. Additionally, I believe that eventual consistency should be enhanced."

"The disc space is lacking. You need to free it up as you are working."

"The secondary index in Cassandra was a bit problematic and could be improved."

"The solution is not easy to use because it is a big database and you have to learn the interface."

"There could be more integration, and it could be more user-friendly."

More Cassandra cons

"I think there are still many Postgres features that can be developed further by the Supabase team."

"There can be compute spikes when we scale up, which we noticed during our intake season while processing millions of records. Massive similarity searches on a lot of vectors can spike the database CPU and potentially slow down API requests, so we had to move to a higher plan in Supabase for handling this during our intake season."

"I notice that the schema visualizer can be improved. Additionally, the internal AI assistant powered by GPT can also be improved."

"I think the support system can be better because after Supabase Vector stopped working in India, there is no support."

"One area for the solution improvement is the inclusion of more sample code in various programming languages, particularly PHP."

Pricing and Cost Advice

"We are using the open-source version of Cassandra, the solution is free."

"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."

"I use the tool's open-source version."

"We pay for a license."

"I don't have the specific numbers on pricing, but it was fairly priced."

"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."

"The solution's cost is reasonable compared to other solutions."
